To all whom it may concern:

Be it known that I, HENRY Fono, al citizen of the United States of America, r'esiding at Detroit, in the county of lVayne and State of Michi n, have invented certain new and useful mprovements in Transmis' thrown out of operative relation by anyshocks imparted to the chassis, and that they occupy' as small spacel as possible without sacrificing accessibility.

This invention relates .to a'power plant.

for an automobile and more particularly to the arrangement of the motor, the ignition generator,`thetransmission or change speed mechanism, and the controlling 'members tliereof to form a compactunit structure which is'not affected by shocks given the chaisof the vehicle, and which while read- A ily accessible takes up little room and is bodil` removable from the vehicle for inspection and repair.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in' the appended claims.

In the drawings, Figure 1 is a view in side elevation partly broken away and in section,

of the driving mechanism or powerv plant with adjacent portions of the frame, of an automobile embodying features of the invention; Fig. 2. is a similar plan view; Fig. 3 is a view in longitudinal V'section in detail, of a change-speed and clutch mechanism; and Fig. 4 is a view in detail. of a brake druin an clutch.

Referring to the drawings, a motor base or crank case 1 is pivotally'suppor'ted at. its forward end on the forward cross 'member 2 of a spring-supported frame-and at its rear end by suitable oppositely disposed lugs 3, or like means, to the side members.- 4, so as to have a three-point support thereon. A motor 5, preferably of.the multicylinder is p aced on'the case with its main s iafi; 6 preferably arranged longitudinally y of the chais. A ily wheel 7 is secured on the main shaft 6 either at or near the end thereof. Preferably the fly wheel has a couformed integrall 'on the end of the motor shaft with its hu 11` constituting in realityr an extension of the motor shaft.

A generator for the ignition circuit of the motor is mounted thereon between the fly wheel and the cylinders of the motor and' preferably consists ofla stationary spider 13 secured to the motor frame and crank case with lfield coils 14 disposed in a ring eoii- 65 cent-ric with the 'inain shaft around ,the

spider rin The flywheel, which forms the rotor of tie generator, has a pluralityof suitably disposed permanent magnets 15 secured on its face by suitable holding means so that the poles sweep by the .ends of the cores f the magnets 14.

A tubular bearing 16 alined with the motor shaft is mounted in the outer end of the casing 1. A sleeve 17 is journaled on 75 the reduced outer end 12 of the ily wheel hub 11 and in the bearing 16 its outer part interiorly squared, polygonal in cross sec' tion, or keyed or spliiied for non-rotatable engagement with one part 18 of a transmisso sion shaft-disposed `longitudinally of the frame, universal joint connections indicated at 19 or like provision being made, 1n the shaft, and the sleeve actin as a support for' the art 18. A driving p ate 20 isseeured'ss on t ie inner end of the sleeve 17 and is con nected b suitable means, as cap screws 21, to a bra e drum-22 which has an extended, hollow hub 23 rotatable on the inner por- ,.tion of the fly wheel hub or motor-shaft ex 90 tension 11, bushings 24 being interposed if desired. The friction drive hub 'forms in effect an extension of the sleeve 17. A

The .transmission shaft extension or sleeve 17 and the drive wheel hub or shaft exten- 95 sion 11 ina becou led to rotate i n unison by a friction clutc of the multiple disk pattern housed in the b rakedi'um 22. In the preferred construction annular thrust plates 25 having notches in theirouter mar- 100 gins engaged by keys or splines 26 on the inner eriphery of the brake drum, are arrange alternately with thrust rings 27 having inner radial lugs 28 engaging key ways or slots in the y 29 keyed or otherwise secured on the outer end of the motor-'shaft extension or fly wheel hub 11. The plates may be forced to gether by a.r push ring 3 1 having studs 32 reciproeable in guide apertures in the-idriv- 110 ing plate 20 that abut fingers 33 pivotedat their outer ends on the .driving plate witln.

periphery of a clutch drum their inner ends in' contact with a shift collar 34 non-rotatable and recprocable on the sleeve 17. rl`he shift collaris "peripherally grooved for engagement.. with a shifting yoke. A spring encir'cling the sleeve and bearing 16, 'in compression between the shift collang-aiulthe bearing and is adapted to normally hold the clutch in engagement.

A transmission or change-speed and re-v versing mechanism, in form a planetary gear train, is mounted on` the tly -wheel and its hub or shaft extension. In the `preferred form and as herein indicated,` a4 reduced forward speed is obtained by a sun `gear 3G journaled on'athe brake drum hub 23 concentric with the fly-wheel hub, that is in mesh with steps 37 of planet pinions journaled'on studs 38 on the side of the fly wheel. The sun gear is locked against rotation by a brake band 39 adapted to be closed on the rim of a plate 40 secured to the gear hub 41, that is preferably extended to brinfr the plate rim side by side with the brake drum 22. Another step 42 ofthe planet pinions 37 is in mesh witha gear 43 formed on or secured to the inner end of the brake drum hub 23, whereby the locking` of the sun gear against rota-tion turns the sleeve 17 at reduced speed. Y Reversal of direction is obtained bya sun gear 44 rotatable on the hub of the slowspeed sun gear 36, a suitable bushing. 15 being interposed if desired. This gear meshes with suitably proportioned steps 46 of the planet pinions and may be locked against rotation by a band 48 encircling a friction drum 49 secured by a plate 50 made fast on the outer end of the gear hub which is arranged so that the drum is disposed side by side with the slow-speed and brake drums. The planet. pinions may be made integrally or be built up of separate steps secured by studs or screws.

A brake lever 51 extending through the upper part of the casin 1 is secured to a rock shaft 52 journaled t iere'in transversely to the motor shaft that passes through slotted ears 53 of the brake band, a c am face on the lever being adapted to force the ears together and therebyr close the band on the brake drum. The slow-speed lever 541 on a transverse Shaft 55 engaging carri 5G of the slow speed drum band and a reverse lever 57 having similar engagement through a transverse shaft 5S and cars 5!) with the band encircling the reverse drum, complete the control system of the change speed train. The shift collar 34 is engaged by a yoke G0 secured on a rock arm 6l connected to a shaft 62 journaled in the casing 1 and adapted to be operated through a link 63 from the slow speed lever or other means within reach of the car operator.

By this arrangement of the arts annit power plant is obtained which 1s bodily removable from the chassis for inspection or repair. Owing to the three-point support of the baseor crank-case and transmission housing in the frame, racking of the latter does not affect the plant and the change speed mechanism is so connected to the motor that it is'impossible for the parts to get out ofline. v may be entirely cut olf from the motor or may be coupled directly thereto independently of the reduction train, or may be made to rotate at slow speed or in reverse when the clutch is disengaged. Furthermore the magneto or ignition generator is a part. of the motor itself and as'the running parts of the motor and the transmission arc coinpletelyhonsed in the crank case or motor casing, oil may be freely applied to theparts and acts as an insulationfor the generator.

As the lever and the control transmission system are connected to shafts journalcd in the case, they cannot become set or bound by vibrations or twisting of the vcar frame so that theiroperation is insured.

Obviously, changes in details of construc tion may bemade withoutl departing from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts..
